abstract
A field experiment entitled, “Residual effect of nutrient management of kharif groundnut on growth, yield attributes, yield and quality of subsequent wheat under organic farming” was carried out during two consecutive kharif and rabi seasons of 2021-22 and 2022-23 on loamy sand soil of Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The nine nutrient management treatments under organic farming applied to groundnut during kharif season were laid out in randomized block design and twenty-seven treatment combinations comprising residual effect of preceding nine nutrient management treatments of groundnut followed by three levels of RDN through organic manure along with cow-based bio-enhancer to wheat tested in spilt plot design with three replications. Growth parameters, yield attributes, yield and quality of wheat after nutrient management treatments of groundnut remained unaffected due the residual effect of various nutrient management treatments under organic farming. 75% RDN through FYM: castor cake: vermicompost (1:1:1) + panchgavya @ 4% spray at 30 and 60 DAS to wheat recorded significantly higher growth parameters, yield attributes, grain yield (2779 kg/ha), straw yield (3926 kg/ha) and quality parameters of wheat. It also gave the highest net return (₹36727/ha).
